Narrows Crossing Armour Rock Back-Filling Works

Scope of work

The QCLNG and APLNG export pipelines cross from the mainland to the liquefaction plants on Curtis Island. They cross at The Narrows which is approximately 10km North of Gladstone. This is within Gladstone Harbour. 2.3km of pipeline crosses from Friend Point on Kangaroo Island to Laird Point on Curtis Island.

MCJV required the 2 x 42 inch pipelines which were installed in the dredged trench to be buried under rock backfill for protection.
